In fact, the working principle of the Heat Pump Hot Water Heater does not differ significantly from the working principle of our air conditioning system. However, our household air conditioners use the cold end (evaporator) of the cooling circuit system; In contrast, heat pumps use the hot end (condenser) of the circulatory system.

The basic principle of heat pump water heater: It mainly consists of compressor, heat exchanger, axial fan, heat storage water tank, water pump, liquid storage, filter, electronic expansion valve and electronic automatic control. After switching on the power supply, the axial fan starts running, the outside air flows through the evaporator for heat exchange, and the reduced temperature air is expelled from the system by the fan. A kind of low pressure working medium gas is compressed into high temperature and high pressure gas and fed to the capacitor. The water forcibly circulated by the water pump also passes through the condenser and is heated by the working medium and fed to the consumer for use. The working medium is cooled to a liquid and the liquid expands. After the valve is throttled and cooled, it flows back into the evaporator. This cycle works repeatedly, and the heat energy in the air is continuously "pumped" into the water, so that the water temperature in the water tank for heat preservation gradually rises and finally reaches about 55°C, which is just suitable for people to take a bath.
Heat pump water heaters are a new thing on the market, and consumer awareness of this is still very low. There are many people who think that it is impossible to get three parts heat with one part heat, and the same applies to other products related to the application of heat recovery technology, although the popularity of heat pump air conditioners was very high.
People's understanding is limited only to the fact that air conditioning is a large electricity consumer, but they do not know that it is more energy-saving than the coal-fired ball furnace. As some larger shopping malls have not yet sold air-powered water heaters, consumer awareness of air-powered water heaters is still very low.
In order to meet these growing requirements, Guangdong JNOD New Energy Technology Co., LTD. has various heat pump water heaters, which allow to increase the products and make them more effective, reliable and consistent.
In recent years, the potential energy of the sports industry under the national fitness, and favorable policies such as swimming into the high school entrance examination sports, the constant temperature swimming pool was once in short supply, and the Swimming Pool Heat Pump was out of stock.
What is the first stage of the workflow of Swimming Pool Heat Pump?
What is the second stage of the workflow of Swimming Pool Heat Pump?
What should we pay attention to when using Swimming Pool Heat Pump?
In the first step, the indoor hot and humid air in the swimming pool first exchanges heat with the outdoor fresh air through the heat exchanger to become warm and humid air, and then the warm and humid air flows through the evaporator, the temperature drops, and the water vapor condenses into cold water droplets and is separated from the air. Make the air dry and realize the function of air dehumidification; at the same time, the heat energy (latent heat and sensible heat) is released in the process of air cooling, water vapor condensation and cooling are absorbed by the refrigerant.
In the second step, the heat energy absorbed by the refrigerant first (latent heat) heats the pool water through the heat exchanger to realize the pool water heating function: the residual heat (sensible heat) passes through the air condenser to heat the cooled indoor air to realize the air insulation function. In the severely cold winter, when the energy available for the heat pump to extract in the air is too small, and the heat energy recovered by the heat pump is not enough to meet the requirements of the indoor air temperature, the auxiliary air heater is added to supplement the heat energy required for the indoor hot air. The Swimming Pool Heat Pump only needs to provide its own operating power, that is, it runs continuously according to the above working procedures, and achieves a harmonious balance of the three functions of pool water heating, air conditioning and dehumidification with low energy consumption.
1. When maintaining and cleaning the Swimming Pool Heat Pump, make sure that the Swimming Pool Heat Pump is in a power-off state. In addition, when the heat pump is not in use: the power supply should also be cut off.
2. Do not use gasoline, Tianna water, volatile oil, solvents and other chemicals, or liquid pesticides on the Swimming Pool Heat Pump, otherwise it may cause parts to crack and deform.
3. The area around the Swimming Pool Heat Pump should be kept dry and well ventilated.
4. Regularly clean the air-side heat exchanger to maintain a good heat exchange effect. If the shutdown time is long, the water in the pipeline of the unit should be drained, the power supply should be cut off, and the protective cover should be put on. When it is necessary to use it again, the system must be thoroughly checked before turning it on.

How does the heat pump water heater achieve the effect of saving energy?
What should we pay attention to when using heat pump water heater?
What are the operational advantages of heat pump water heaters?
When the heat pump water heater is working, the energy QA stored in the ambient medium is absorbed in the evaporator; it consumes a part of the energy itself, that is, the compressor consumes power QB; the heat release QC is carried out in the condenser through the working fluid circulation system, QC=QA+QB, it can be seen that the energy output by the heat pump is the work QB done by the compressor and the heat QA absorbed by the heat pump from the environment; therefore, the use of heat pump technology can save a lot of electric energy.
temperature, water consumption
Put the bath water in the heat pump water heater. The most suitable water temperature is 42°C. It can be slightly higher by 1-2°C for middle-aged and elderly people. The water for showering is about 40~50 liters per person. Bathtubs and Jacuzzis are determined by capacity.
How much hot water can be made
In terms of product performance and theory, the heat pump water heater can be cycled back and forth to continuously produce hot water. Under normal temperature, the hot water can be produced per hour as follows (45℃-55℃): It depends on the size of the unit.
The heat pump water heater absorbs the low-temperature heat in the air, vaporizes it through the fluorine medium, and then compresses it through the compressor to heat up and pressurize it. The air energy water heater has the characteristics of high efficiency and energy saving. The same amount of hot water produced is 4-6 times that of the electric water heater. Its annual average thermal efficiency ratio is 4 times that of the electric heating, and the energy efficiency is high.
The heat pump water heater overcomes the shortcomings of solar water heaters that rely on sunlight for heating and inconvenient installation. Since the work of the air energy water heater is to exchange heat through the medium, it does not need the electric heating element to be in direct contact with the water, which avoids the danger of electric water heater leakage, and also prevents the gas water heater from the danger of explosion and poisoning, and more effectively controls the gas Air Pollution Caused by Exhaust Gases from Water Heaters.

Compared with ordinary central air conditioning refrigeration and gas wall-hung boiler heating, what are the advantages of Heating and Cooling Heat Pump?
What are the advantages of using the Heating and Cooling Heat Pump?
What is the working principle of Heating and Cooling Heat Pump?
The common heating and cooling equipment on the market is mainly fluorine system heating and cooling air conditioning or the combination of gas wall-hung boiler heating and central air conditioning refrigeration.
The main advantage of Heating and Cooling Heat Pump compared to ordinary heating and cooling air conditioners is high comfort. The fluorine system heating and cooling air conditioner directly controls the indoor temperature through the flow of the refrigerant, and the refrigerant directly exchanges heat with the air. This heat exchange method has two disadvantages: First, the temperature of the air outlet of the air conditioner is very low or very high (7°C-12°C during cooling, 40°C-50°C during heating), the body feels very bad, and it is bitingly cold in summer. The winter is hot and dry; second, although the fluorine system air conditioner has a relatively fast cooling and heating speed, it will also cause a large amount of moisture in the air to be taken away due to the rapid heating and cooling speed, resulting in excessive indoor dehumidification and drying.
1) The unit of Heating and Cooling Heat Pump has high energy efficiency ratio, energy saving and electricity saving.
2) The water temperature of the Heating and Cooling Heat Pump is generally constant at 12-22°C, which is 7°C for the water supply in summer, 12°C for the return water, 45°C for the water supply in winter, and 40°C for the return water, and the temperature difference between them is small. , so the unit has less work and more energy.
During the operation of Heating and Cooling Heat Pump, the evaporator absorbs heat from the ambient heat energy in the air to evaporate the heat transfer working medium. After the working medium vapor is compressed by the compressor, the pressure and temperature rise. When the high-temperature vapor passes through the special annular pipe bonded on the outer surface of the water storage tank, the condenser condenses into liquid and transfers the heat to the water in the water storage tank of air source heat pump.

Some customers may ask what’s the different between Residential on/off and inverter swimming pool heat pump.
It is very similar to the concept of air conditioning inverter technology.
On/Off is defined as “all or nothing “,the input power or the heating capacity keeps the same.
For the inverter system ,Unlike ON/OFF heat pump with single-speed compressor which by switching on and off periodically to adjust the performance of the heating & cooling, full inverter heat pump uses a variable speed compressor which can automatically adjust the output needed at the lowest consumption of power and maintain the best temperature at different climatic conditions. When the heating demand is high, the inverter compressor and the fan motor will start running at a high speed, inversely, they will run at a low speed.
The advantages included:
1.Achieve an extremely high COP.
2.Shorten heating time.
3.Greatly save energy and cut down electricity bill.
4.Contribute to a quiet neighbor environment.

JNOD are selling R32 inverter swimming pool heat pump, its heating capacity ranges from 5.5-32Kw. So, it will be a problem for user or wholesaler to choose the suitable heating capacity for different pool sizes. Let us show you 2 methods to choose the suitable.
If you do not want to do complicated calculations and do not take into account extreme weather, you can use the following formula: 3KW for 10m³. For example, if you want to heat a 30CBM pool, (30 CBM÷10CBM)* 3KW = 9KW . So, you can choose the 9.5Kw model.
This method is used to do a very precise calculation on the heating capacity, considering the heating time, water temperature, ambient temperature, etc.
* Step 1: Calculate the needed heating capacity
In the calculation, we usually set the outlet water temperature at 28℃, primary heating time usually is 48hours.
Formula will use: Q=1.163*△t*V ;
W=Q/T
Explanation: Q = Heat Demand (KwH)
△t = Temperature Difference (℃)
V = volume of pool (m³)
W = Heat pump capacity(Kw) - usually will add 15-25% of heat loss
T = Hours for heating (H)
Example: A swimming pool 10*4*1.5m, original temperature is 18℃
Answer: set the target temperature into 28℃, heating hour into 48 hours
Q = 1.163*(28-18)*(10*4*1.5)=697.8 KwH
W= (1+15%) *Q/T=1.15*697.8/48=16.72 KW
*Step 2 : Choose the suitable heating capacity depending on working condition
The heating capacity of a heat pump is not constant; it changes with the ambient temperature. Therefore, after calculating the required heating capacity, we also need to choose the model we need according to the ambient temperature.
Still that sample, we calculate that 16.72Kw is needed. If the ambient temperature is around 24-27℃, you can choose the 17.5Kw model; if ambient temp is around 12-15℃, better to choose 25kw model.

Ambient Temperature:(DB/WB)27℃/24.3℃ | |||
Heating Capacity (kW) | 4.34~18.1 | 4.72~21.21 | 5.05~25.28 |
